Quantum corrections to spinning superstrings in AdS 3 × S 3 × M 4 : determining the dressing phase

A bstractWe study the leading quantum string correction to the dressing phase in the asymptotic Bethe Ansatz system for superstring in AdS3 × S3 × T4 supported by RR flux. We find that the phase should be different from the phase appearing in the AdS5 × S5 case. We use the simplest example of a rigid circular string with two equal spins in S3 and also consider the general approach based on the algebraic curve description. We also discuss the case of the AdS3 × S3 × S3 × S1 theory and find the dependence of the 1-loop correction to the effective string tension function h(λ) (expected to enter the magnon dispersion relation) on the parameter α related to the ratio of the two 3-sphere radii. This correction vanishes in the AdS3 × S3 × T4 case.

Quantum corrections to short folded superstring in AdS 3 × S 3 × M 4

A bstractWe consider integrable superstring theory on AdS3 × S3 × M4 where M4 = T4 or M4 = S3 × S1 with generic ratio of the radii of the two 3-spheres. We compute the one-loop energy of a short folded string spinning in AdS3 and rotating in S3. The computation is performed by world-sheet small spin perturbation theory as well as by quantizing the classical algebraic curve characterizing the finite-gap equations. The two methods give equal results up to regularization contributions that are under control. One important byproduct of the calculation is the part of the energy which is due to the dressing phase in the Bethe Ansatz. Remarkably, this contribution
